High Surf Advisory for south shores
HONOLULU (KHON2) – A stable, light to moderate trade wind flow will continue through Sunday.
The trades will remain down from the past few days as the pressure gradient south of broad North Pacific surface high pressure stays relaxed due to a front far north of Hawaii.
Aside from areas of thin high clouds, an upper-level trough parked over the region will have little effect.
Diffuse bands of moisture moving along the trade wind flow will focus modest rainfall along windward slopes, and a band passing through late tonight and Sunday will mainly affect Kauai and Oahu.
Aside from afternoon showers on the Big Island and Kauai, leeward areas should remain rather dry.
Subtle changes are expected Monday and Tuesday.
The above mentioned upper-level trough will deepen west of the state and induce a surface trough several hundred miles northwest of Kauai.
The current south southwest (200 degree) swell will bring large breaking surf to all south facing shores through the day Sunday, then gradually decline early next week.
A High Surf Advisory is in effect for south facing shores through 6 PM HST Sunday.
No other significant south swell sources expected through the remainder of next week.
